Here's an American classic: calcite from North Vernon, Indiana, with marcasite inclusions making them glitter in the light.

And speaking of light, this piece just glows an awesome honey color in the sun, with the zoning just adding something neat to these crystals. The white cores make you think of frog eggs a little bit no?
